A networking device including a plurality of client ports arranged for communicating with a plurality of clients, a service port arranged for communicating with a machine arranged to communicate with the plurality of clients, and networking componentry arranged to communicate electromagnetic communications between the plurality of client ports and the service port.

System and method for supporting flexible forwarding domain boundaries in a high performance computing environment. In accordance with an embodiment, flexible forwarding domain boundaries can be supported by dividing/partitioning a physical switch into two or more logical switches, where each switch is logically in a different domain, and allowing a fabric to be decomposed into independent subnets with one two or more physical end ports at the physical switch. By doing so, the same hierarchical forwarding structure and management structure between subnets can be provided as when complete physical switches are used as building blocks.

The present disclosure is directed to systems and methods for connecting hosts to any router by the use of bridges. Example implementations described herein are directed to determining connections between routers and hosts based on the topology of the NoC and cost functions. Unused routers may also be removed from the NoC configuration and unused directional host ports of routers may be utilized to connect hosts together depending on a cost function and the desired implementation.

A method for creating a port group, includes generating, by a first software defined network (SDN) controller, the specified identifier according to a device identifier of a first forwarding device in a preset path, a device identifier of a last forwarding device in the preset path, and a device identifier of a specified forwarding device in the preset path; and sending, by the first SDN controller, the specified identifier to a second SDN controller, so that the second SDN controller creates, on the specified forwarding device, a specified port group corresponding to the specified identifier. Therefore, the first SDN controller needs to interact with the second SDN controller only once, to create a port group on the specified forwarding device that is directly controlled by the second SDN controller, and thus the port group creation process is simple.

A method for establishing a temporal label switched path (T-LSP) implemented in a node in a network. The method includes receiving a path request including a time interval and a set of constraints; obtaining traffic engineering information from a first database; computing, by the node, a path satisfying the time interval and the set of constraints based on the traffic engineering information obtained; storing the time interval and the set of constraints in a second database; and instructing an ingress node of the temporal LSP to signal the temporal LSP in the network along the path computed at a start of the time interval identified in the path request and to tear down the temporal LSP at an end of the time interval identified in the path request.

A storage system switching mediators within a storage system synchronously replicating data, where the switching between mediators includes: determining, among one or more of the plurality of storage systems, a change in availability of a first mediator service, wherein one or more of the plurality of storage systems are configured to request mediation from the first mediator service; communicating, among the plurality of storage systems and responsive to determining the change in availability of the first mediator service, a second mediator service to use in response to a fault; and switching, in dependence upon the change in availability of the first mediator service, from the first mediator service to the second mediator service.

The disclosure provides for a system that includes a network controller. The network controller is configured to receive information from nodes of a network, where nodes include one node that is in motion relative to another node. The network controller is also configured to generate a table representing nodes, available storage at each node, and possible links in the network over a period of time based on the information, and determine a series of topologies of the network based on the table. Based on received client data including a data amount, the network controller is configured to determine flows for the topology. The network controller then is configured to generate a schedule of network configurations based on the flows, and send instructions to the nodes of the network for implementing the network configurations and transmitting client data.

Embodiments include methods, systems, and computer program products for routing mode selection in a switched fabric network. A fabric login request including a fabric login payload is received at a network device to establish communication parameters with a switched fabric network. The network device can determine whether the fabric login payload includes an extension for routing policy support and whether a current routing policy of the network device is compatible with a routing mode defined in the fabric login payload based on the extension for routing policy support. The fabric login request can be rejected based on determining that the current routing policy of the network device is incompatible with the routing mode defined in the fabric login payload. The fabric login request is completed based on determining that the current routing policy of the network device is compatible with the routing mode defined in the fabric login payload.

A computing platform executing an application may receive a response to a request for opening a network port for utilization by the application from a computing platform distinct from the computing platform executing the application. The computing platform executing the application may determine whether to open the network port for utilization by the application based on the response to the request. In some embodiments, the application may invoke at least one call to an application program interface (API) of an operating system (OS) running on the computing platform executing the application, and the request may be generated responsive to the at least one call to the API of the OS.

A method and system for automatic redirection of control channel messages in response to a control channel failure with a target switch in a software defined networking (SDN) network, the automatic redirection occurring before a topology of the SDN network is updated in response to the control channel failure. The method includes determining whether a control channel message is to be sent to an SDN controller, checking availability of the control channel, selecting a backup port to reach the SDN controller in response to the control channel being unavailable, and forwarding the control channel message to the SDN controller via the backup port.
